hardcoded registers for the most part)
+ added extra g_exception_discard_reason() that can be called when we only
want to get rid of the currently pushed exception reason, and don't have
to load it (so it can do nothing on platforms that don't use push/pop)
git-svn-id: branches/hlcgllvm@28481 -
so that if a_loadaddr_ref_reg() is used to load the address of a procdef
into a register, the getpointerdef(procdef) won't (wrongly) result in two
*'s
o the previous behaviour was necessary for the tck_simple_procvar2proc
special case that was removed in the previous commit
git-svn-id: branches/hlcgllvm@28477 -
procdef.getcopyas(procvardef,pc_address_only) as the def if we want to
specify that we're interested in the address of a procedure/procvar of
object
git-svn-id: branches/hlcgllvm@28476 -
sinttype (they're the same on most platforms, except on 8 bit ones where
ossinttype is still 16 bit)
* simplified and documented second_length(), and fixed some (harmless)
errors in the used tcgsize for the resultdef (it had to be OS_SINT
rather than OS_INT -- now it's just def_cgsize(resultdef) so it's
always correct)
git-svn-id: branches/hlcgllvm@28387 -
be included at the start of the implementation of the system unit (before
the rest of except.inc)
* catch declarations in/loading from the system unit of the TExceptAddr type
* use this type instead of hardcoded size constants in the compiler
* in generic code that is active for all targets, puts its use in a virtual
method since it's only valid for targets using setjmp/longjmp-style
exception handling (and the record is not defined at all in the JVM RTL)
git-svn-id: branches/hlcgllvm@28376 -
o results in simpler code, and more importantly is required for some code
that expects a LOC_REGISTER after calling certain system unit helpers
(e.g. in ncgutil.new_exception)
git-svn-id: branches/hlcgllvm@28375 -
o there are no cpu registers on the llvm target, but generic code may still
occasionally allocate them via the generic routines in case of e.g. a
hardcoded use of a function return register
git-svn-id: branches/hlcgllvm@28373 -
second_int_to_bool() and second_bool_to_int() for certain cases, do the
same for their first_*() variants in first_bool_to_bool() so that the
expectloc is correctly initialised
o since first_int_to_bool can now be called for bool_to_bool to, make
sure we correctly handle is_boolean(left.resultdef) in that case
(integers cast to a smaller boolean type ignore the upper bits,
while with boolean to boolean they are taken into account
git-svn-id: branches/hlcgllvm@28369 -
have to emit the label we originally allocated for the fallthrough path (otherwise
the branch is not inverted at all, and moreover the caller will also emit the
original target label somewhere so it will be doubly defined)
git-svn-id: branches/hlcgllvm@28367 -
r28315 introduced an arm optimization which requires
tst rX, #imm
to work. This is not available on 16bit thumb, I've disabled that
optimization on thumb for now.
